-23. (canceled)
A filling system for filling a liquid medium, in particular an urea solution, into a vehicle tank with
- a filling device with a filling pipe and a fill level sensor on said filling pipe, wherein the fill level sensor emits a fill signal when the fill level sensor detects the liquid medium
- a delivery pump for delivering the medium to the filling device, and
- a control device, which is designed to switch off the delivery pump when a fill signal is received and to switch the delivery pump back on when the fill signal is no longer received after a specified period of time.
A method for filling a vehicle tank with a liquid medium, in particular an urea solution, comprising
- connecting a filling device to said tank, said filling device comprising a filling pipe and a fill level sensor on the filling pipe for emitting a fill signal when the fill level sensor detects the liquid medium,
- operating a delivery pump for delivering the medium to the filling device, deactivating said delivery pump when a fill signal is received, and
- reactivating said delivery pump when the fill signal is no longer received after a specified period of time.
